# Disable k3s-agent on pi.prole.org and remove it from the cluster.
|
|
# Safe to run against a live cluster — only touches pi.prole.org.
|
|
# Storage (iSCSI) and pihole configuration are intentionally preserved.
|
|
#
|
|
# Usage:
|
|
# ansible-playbook -i inventory/hosts.ini playbooks/disable_pi_k3s.yml
|
|
# ansible-playbook -i inventory/hosts.ini playbooks/disable_pi_k3s.yml --check
